Chapter 16, Problem 16.10P
If the water table in Problem 16.9 drops down to 0.25 m below the foundation level, what would be the change in the factor of safety for the same gross allowable load?
16.9 A square footing is shown in Figure 16.18. Determine the gross allowable load, Qall, that the footing can carry. Use Terzaghi’s equation for general shear failure (Fs = 4). Given: γ = 17 kN/m3, γsat = 19.2 kN/m3, c′ = 32 kN/m3,

Oil of sp.gr. 0.9 flows through a vertical pipe (upwards). Two points A and B one
above the other 40 cm apart in a pipe are connected by a U-tube carrying mercury. If
the difference of pressure between A and B is 0.2 kg/cm²,
1- Find the reading of the manometer.
2- If the oil flows through a horizontal pipe, find the reading in manometer for the
same difference in pressure between A and B.
